Application filed January 9, 1912. Serial No. 670,270.

To /z/Z wlw/n 'it 'may concern.

Be it known that I, Amano L. motion, citizen o't'the United States7 residing' at St. laul, in the county et ltatnscy and tltate ol. hilinnesota, have invented certain :new and uset'ul Improvements in Harrow rltttachments for lflows7 oit which the :Following is a specification.

This invention relates to harrow attachinents especially adapted to be used in conjunction with breaking;` or turning plows, and has :tor its object to providi an attachinent oit simple structure which may be easily and quickly applied to the plow and which will operate upon the soil, as the saine is heine; turned for the purpose ot pulverizing the saine, whereby a tine dust Inulch is produced at the surface oit' the soil4 a'l'ter the plowing operation.

A further object oi the invention is to provide in an attachment ogt the character indicated means t'or whippingor heating` the soil so that the reduction of the sanne to line particles may he more readily and quickly accomplished.

Another object of the invention is to provide means tor holding,` the attachment so that thc soil engaging n'icinhers will operate ata desired depth in the furrow slice as it turned by the plow.

While the attachment is designed `primarily to he used in connection with a turning or breaking plm i as .indicated7 it may be applied equally as advantageously to a cultivator or other soil working implement or machine.

A still :further object ot' the invention is generally to improve this class ot devices so as to increase their utility7 durability and efficiency.

Further objects and advantages will appear in the 'tolloivii'ie description, it being understood that various changes in form, proportions and minor details ot construction may be resorted to within the scope of the appended claims.

For a t'ull uuderstainling ot the invention reference is to be, had to the 'following description and aceoinpanyiinel drawings, in which Figure 1 a sido elevation ot a plow with the harrow attruzhnient applied; 'Figi'. 2 is a rear elevation ot the saine; Fig'. l is a transverse sectional view 1 part oit the attachineut cut on the line 23--3 ot Fie'. 2.

Corresponding; and like parts are referred to in the lollowinp,` description. and indicated in all the views o'l the accompanying drawings by the saine rcterenee characters.

.ts illustrated in the accoinpaliving drawings the harrow attachment is shown applied to a breahine plow which includes a lundsido plate 1, inoldboard 2, share 3 and handles -it of the usual pattern and ar angelnent.

'lhc attiuhnient includes a plate (S which is secured at its upper portion lo one of.' the handles fland at. its lower portion to the landsde plate A1. This plate is provided with an arcuate slot T and upon its upper portion with a serie-A o'lE iiulentalions S. siinilar plate t) is secured to the nioldboard L) at itz-1 lower portion and to the other handle vlA at its upper portion. This plate is provided with an arcuate sl ot which corresponds willi the slot T in the. plate t3, but the plate 5) is devoid olf indenlalions at its upper edge portion. The plates t3 and t) are in parallel relation to eaeh other and spaecd troni each other. il. shalt l() is iournaled at its ends in the plates (i and t). i\ traction `wheel 1lA is fixed to the sha'lt l() between the plates (l and Sl and is provided upon its periphery with a series ot tractors 'l2 ot any suitable size and length. it gear wheel l-S is fixed to the sha'tt l() at one side ot' the traction wheel ill.

i\ bar 'tlis provided with two sets oit lugs to and ttt. rlhese lues are adapted to receive between thcln handles ft. and securiingl bolts lT pass transversely through cach pair otl lues and each handle l. l`he bar l=l projects beyond the handle lwhich is located at the lurrow slice side ol the plow and at its eX- trelnitv is anpgularly disposed, as at '18. A plate t) is provided with an elongated slot :2l which rereive;-- a bolt 32. The said bolt is screw threaded into euu'an'einent with the extremity 18 of the bar 1st. The outer end ot a sha l'l il?, is journaled at the. lower rear end olE the plate 2l and the inner portion ot the sha'lit i2?) passes through the arcuate slots in the plates t and t.) and the inner end ot" the said shalt is journaled in a bearingl 2li; which is slidably mounted upon the plate. r\ .sel screw 2.5 passes through the side ot the bearing' il and is adapted to he en e'ag'ed with an)v one otl the iiulentatituis S provided at the upper edge oi the said plate (t.

il. wheel 2C is fixed to the sha'lt. Q3 at a point betwveeu the plates (l and' t) and is provided at one side. with a series olf outstanlliinel pins 27 upon cach one ol. which is ends with longitudinally disposed slots 31 Aand being provided at 'their ends with inturned extremities 32. The members of veach pair are positioned one at each side of the shaft 23, and pins 33 pass transversely through the shaft and are located at their end portions in the slots 31 of the plates. These pins 33 are designed to prevent the plates from having excessive movement longitudinally7 but will permit slight longitudinal movement of the said plates in order that they may flex or bend when they are subjected to strain during the operation of beating or breaking the soil. Teeth 34 are arranged in pairs the members of which are diametrically opposite each other with relation to the shaft 23 and radially disposed with relation to the said shaft. These teeth are provided at their inner end portions and at their opposite sides with recesses 35 which receive the inturned extremities 32 of the plates 30. Securing bolts 3G pass transversely through the plates 30 and the inner end portions of the teeth 34.

Throughout the series of soil engaging members mounted upon the shaft 23 the teeth of one set of soil engaging members kare disposed at right angles to the teeth of the next adjacent set or sets and this relation is maintained throughout the entire series. The soil engaging members are located beyond the outer or rear edge of the moldboard 2 of the plow and consequently they are positioned directly over the path into which the furrow slice is turned by the said inoldboard.

As the plow to which the attachment is applied moves in a forward direction and turns a furrow slice, the wheel 11 travels along the bottom of a furrow and the tractors 12 engage the bottom of the furrow and break the same, thereby serving as means for operating upon the sub-soil. As the wheel 11 rotates t-he shaft 10 rotates with the same which carries aro-und the wheel 13. Inasmuch as the rollers 28 upon the pins 27 engage the wheel 13, the wheel 26 is rotated in the opposite direction from that in which the wheel 11 rotates. Therefore the shaft is rotated so that its upper part moves rearwardly as the plow moves in a forward direction. The shaft 23 carries the teeth 34 around in the saine direction and as the said teeth strike the furrow slice which is being turned by the moldboard 2, the material of the said slice is reduced so that the slice is effectually broken. ris the teeth 34 strike the furrow slice the pla-tes 30 to which they are at-ttached may give so that the plow and the attachment is not subjected to undue vstrain due to the impact of the teeth against the furrow slice. At the same time should the teeth strike rock or other obstruction the said plates 30 will give sufficiently to permit the teeth to pass over t-he obstruction without injury.

The object in providing the slots 7 in the plates 6 and 9 and also the slotted plate 21 is that the shaft 23 may be moved to a desired distance behind the axis of the shaft 10 and that the teeth 34 may operate at a desired depth in the furrow slice. By removing the wheels 13 and 26 and substituting others of different diameters, the shaft 23 may be rotated at any desired speed with relation to the rate of rotation of the shaft 10.

When it is desired to use the plow without the harrow attachment, all of the parts Aexcept the plates 6 and 9 may be removed and these plates may be retained upon the plow inasmuch as they are so positioned that they will not interfere with the operation of the plow when the saine is used for turning the soil only. 1f desired an additional traction wheel 11 may be mounted upon the shaft 10, and in such case the traction wheels would be at the opposite side of the wheel 13 and a seat or seat post may be connected with the attachment or the plow so that the attachment may serve as an ordinary harrow cart.

Having thus described the invention, what is claimed as new is:

1. The combination with a turning plow comprising a land-side and a mold-board, of vertically disposed supporting plates secured to the land-side and the mold-board,

a bar supported above said plates and ex-v comprising a land-side, a mold-board andhandles projecting rearwardly therefrom, of'

supporting plates secured to the land-side and the mold-board in rear of the same, a

bar secured to the handles and extending laterally beyond the same and the moldboard, a plate adjustably secured to the outer end of the said bar, a shaft having one end j ournaled in the said plate and equipped with bearings adjustably mounted in the plates secured to the mold-board and the land-side respectively, a driving shaft joui naled in the lower portions of said plates, a

11 traction Wheel on said shaft, a gear wheel on said shaft, and a crown wheel on the rstmentioned shalt meshing directly with the said gear wheel.

In testimony whereof, I aflix my signature 1n presence of two witnesses.
